Plants annual; tufted. Culms 6-80 cm, erect or ascending, pilose or villous. Leaves pilose or villous; sheaths open nearly to the base; auricles absent; ligules truncate, erose, ciliate, abaxial surfaces densely pubescent; blades flat at maturity, convolute in the bud. Inflorescences terminal panicles, dense, ovoid. Spikelets laterally compressed, with 1 floret; rachillas prolonged beyond the base of the floret, pubescent; disarticulation above the glumes, beneath the floret. Glumes 2, equal, exceeding the florets, lanceolate, membranous, pilose, hairs 2-3 mm, 1-veined, veins acuminate and awned, awns pilose; calluses blunt, pubescent; lemmas lanceolate, pilose or scabridulous, 3-veined, 3-awned, apices bifid, lateral-veins extending as slender awns, not twisted below, central awn arising from the distal 1/3 of the lemma, twisted below; paleas nearly as long as the lemmas, veins scabridulous, extending as awnlike points; lodicules 2, narrowly elliptic, glabrous, apices minutely bilobed; anthers 3; ovaries glabrous; styles fused or separate. Caryopses stipitate, subterete, ellipsoid; hila 1/5-1/4 as long as the caryopses, ovate, x = 7.
